The American Precision Arms G2F5838N Gen 2 Fat Bastard Self Timing Brake is engineered for serious precision rifle shooters running powerful .338 caliber platforms. Machined from high-grade stainless steel and finished in a durable black nitride, this muzzle brake uses a self-timing design with a separate locking nut, allowing quick, repeatable installation without crush washers or peel washers. Its multi-port body and generous 1.115" diameter work together to help manage recoil and muzzle rise on larger barrels typically found on .338 Lapua and similar cartridges.

With 5/8"-24 tpi threads and a 3.30" overall length, this brake is purpose-built for heavy rifles where control and consistency matter most. Ideal for long-range range work, precision competition, and dedicated training rifles, it offers a practical way to stay on target and spot impacts more easily. The thoughtful design and clean machining reflect American Precision Arms’ reputation for quality, innovation, and shooter-focused engineering.
